By default Name field of a meeting in Sugar has size limit of 50 characters. This is pretty strong limitation. For example, John Smith (Contoso) / Julia White (Company) / Scoping discussion exceeds this limit by 15 characters. When such a meeting is synchronized from Exchange mailbox to Sugar - it's subject is truncated.

Meeting subject truncation may lead to duplicates. If another user has same meeting in Exchange mailbox then during synchronization matching meeting will not be found in Sugar because of subject and duplicate item will be created in Sugar.

To increase Name field size limit in Sugar open Studio, navigate to Meetings module, choose Fields and then Name field. Update Max Size to greater value, e.g. 150.
